## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability jithox-peppol-participant-lookup-a07dc736 -d '<json body>'
```

Example prompt: Check if the company with Peppol participant ID '0088:5790000436057' is registered on the Peppol network and whether they support BIS 3.0 invoices — I need a clear go/no-go before I send them an e-invoice.

## When to prefer this

Use this endpoint when you need a definitive, machine-readable go/no-go decision on whether a trading partner is reachable via the Peppol network before attempting e-invoice delivery. Prefer it over manual SMP lookups or generic VAT checks when you specifically need Peppol network membership and BIS 3.0 support confirmation with a signed audit receipt. Ideal for automated AP/AR workflows where human review must be minimized.

## Known failure modes

- Participant ID not found in Peppol directory — returns unregistered status with blocking reasons
- Malformed or invalid Peppol participant identifier format — returns validation error
- Payment not accepted (x402 payment failure) — call not executed
- Network timeout reaching Peppol SML/SMP — may return error or stale data
- Unsupported identifier scheme — returns decision with warnings and requiresHumanReview flag

## How this service works

Decision-grade VAT, VIES, Peppol and invoice readiness for AI agents: five read-only MCP tools that return one machine-readable decision with a signed receipt. Public self-service: free trial, then pay per accepted call.

## Output

Returns a JSON object with the participant's Peppol registration status ('registered' or otherwise), a boolean indicating BIS 3.0 invoice support, and a structured decision envelope containing canProceed flag, human-readable summary, any warnings, blocking reasons, required next actions, and a requiresHumanReview flag — all signed with a receipt for audit purposes.
